Description
GOVERNMENT INTEREST

The embodiments described herein may be manufactured and used by or for the Government of the United States of America for government purposes without the payment of any royalties thereon or therefore.

BACKGROUND Technical Field

The embodiments herein generally relate to explosive systems, and more particularly to modular shaped charge system (MCS) explosives.

Description of the Related Art

Conventionally, shaped charges are used in guns. A shaped charge typically includes a housing component, an explosive head portion, and a liner that retains the explosive portion within the housing component. A charge detonates and launches a metal projectile towards a main charge, which then detonates upon impact. This action collapses a metal shaped charge liner, which is projected forward through the mechanical impact fuze and into the target. At the same time the main charge fragments the body of the grenade and throws those fragments outward.
